Abstract
An optical pickup actuator and an optical recording and/or reproducing apparatus and method using the same. The optical pickup actuator includes a blade, a plurality of suspensions, first and second coil members, and a magnet member. An objective lens is placed on one side of the blade. Each of the suspensions is coupled at one end to the blade and fixed at the other end to a holder provided at one side of a base, such that the suspensions movably support the blade. The first and second coil members are installed on the base to be separated from each other, with the magnet member being installed on the blade between the first and second coil members.
